What measurement tool helps a project manager assess productivity by checking story points in previous iterations?

The velocity chart is a valuable tool for project managers, especially in Agile environments, as it measures a team's productivity by tracking the number of story points completed in each iteration or sprint. By analyzing the velocity over multiple iterations, project managers can gain insights into the team's performance, identify trends, and make informed predictions about future iterations.

The velocity helps in understanding how much work a team can typically complete in a given time frame, allowing for better planning and forecasting of project timelines and deliverables. This measurement is essential for Agile methodologies, where iterative progress and adaptability are central to success.

In contrast, other charts like the throughput chart, burnup chart, and burndown chart serve different purposes. Throughput charts focus on the number of completed tasks over time, while burnup and burndown charts track work completed versus work remaining, but they do not specifically measure the story points completed like the velocity chart does.
